What work will a current of 2 A do in 5 minutes with a voltage in the circuit of 15 V?

Initial data: I (value of the current in the circuit) = 2 A; t (time of passage of electric current through the circuit) = 5 min; U (voltage at the ends of the circuit) = 15 V.

SI system: t = 5 min = 5 * 60 s = 300 s.

The work that the electric current will perform is calculated by the formula: A = U * I * t.

Let’s calculate: A = 15 * 2 * 300 = 9000 J or 9 kJ.

Answer: The current will be able to perform work equal to 9 kJ.
